Key operating and financial metrics for the Company include:

OUTLOOK

In 2026, the Company expects to receive or accrue payments on 3,500 to 4,500 attributable GEOs⁽¹⁾⁽²⁾. The lower end of the range reflects current operating assumptions and known constraints, while the upper end incorporates potential impact of improved grades, continued ramp-up of key assets, and contributions from new sources of cash flow. Primary sources of cash flows from royalties and streams for 2026 are expected to include Tocantinzinho, Wharf, Aranzazu, Endeavor, La Encantada, La Guitarra, and based on operator disclosures, the Company also expects to receive initial cash flows in 2026 from Amalgamated Kirkland and La Parrilla.

Attributable GEOs are expected to be weighted towards the second half of 2026, reflecting the timing of higher-grade production and the continued ramp up of key assets.

Achievement of guidance will be influenced by the following:

• Wharf deliveries are expected to be lower in the first half of 2026, with crushing capacity anticipated to be restored in the second quarter of 2026;
• Tocantinzinho deliveries are expected to be more heavily weighted to the second half of the year, as higher grade ore is scheduled to be mined under the mine plan;
• Deliveries from Endeavor are expected to increase progressively over the course of the year as operations continue to ramp up; and
• Relative price performance of gold versus other commodities and the resulting impact on GEO calculation.

ASSET UPDATES

Below are updates during the three months ended December 31, 2025, and subsequent period to certain of the Company’s assets, based on information publicly filed by the applicable project owner:

Tocantinzinho

On March 12, 2026, G Mining Ventures Corp. (“G Mining“) provided its year-end Mineral Reserves and Resources at Tocantinzinho which consisted of Proven and Probable Reserves of 1.87 Moz of gold at a grade of 1.17 g/t contained in 49,784 kt, and Measured and Indicated Resources of 1.92 Moz gold at a grade of 1.25 g/t within 47,665 kt. G Mining also stated the 2026 exploration budget for Tocantinzinho is set at $8-10 million with the intent discovering the next deposit within the Tocantinzinho land package.

On January 20, 2026, G Mining provided its 2026 and 2027 operational outlook at Tocantinzinho, where it expects to produce 160–190 koz of gold in 2026, with approximately 62% of production expected in the second half of the year as higher-grade mineralization becomes available in accordance with the mine plan. Gold production in 2027 is expected to range between 200–235 koz of gold, driven by the contribution of a full year of higher-grade Phase 2 ore at Tocantinzinho.

On January 13, 2026, G Mining reported fourth quarter Tocantinzinho gold production of 47.3 koz and gold sales of 47.5 koz, for total full-year 2025 results of 172 koz produced and 172 koz sold.

Metalla accrued 357 GEOs from Tocantinzinho for the fourth quarter of 2025 and 1,293 GEOs for the 2025 fiscal year.

Metalla holds a 0.75% GVR royalty on Tocantinzinho.

Wharf

On February 18, 2026, Coeur Mining, Inc. (“Coeur“) reported fourth-quarter gold production of 24.8 koz at Wharf. A fire incident occurred at Wharf’s tertiary crusher in the fourth quarter of 2025, resulting in lower ore tonnes placed on the heap leach pads. Coeur added temporary crushing capacity to help mitigate the reduction, and it expects a new crushing system to be installed during the second quarter of 2026. Coeur also released its full-year 2026 guidance for Wharf, where it expects to produce 72–90 koz of gold with production expected to steadily increase throughout the year as crushing capacity is restored. Coeur also announced it expects to spend $10-$12 million on exploration in 2026.

On February 17, 2026, Coeur announced an updated technical report for Wharf that nearly doubled the mine life to approximately 12 years. Proven and Probable Mineral Reserves at Wharf increased by 65% to 1.25 Moz of gold at a grade of 0.71 g/t, contained within 55.1 Mt, and Measured and Indicated Resources of 61.8 Mt at 0.6 g/t for 1.19 Moz gold. Coeur stated that Wharf remains positioned for additional meaningful mine life extensions, with a total Inferred resource estimate of 72.9 Mt at 0.63 g/t for 1.49 Moz gold.

Metalla accrued 147 GEOs from Wharf for the fourth quarter of 2025 and 825 GEOs for the 2025 fiscal year.

Aranzazu

On February 26, 2026, Aura Minerals Inc. (“Aura“) reported fourth quarter production from Aranzazu of 18,878 GEOs (as defined by Aura), marking a 12% decrease over the third quarter of 2025, resulting mainly from metal prices as higher gold prices negatively impacted the conversion to GEOs (as defined by Aura). Aura stated that at constant prices, Aranzazu production was in line with Q2 2025 and 4% higher than Q3 2024.

Metalla accrued 156 GEOs from Aranzazu for the fourth quarter of 2025 and 678 GEOs for the 2025 fiscal year.

Metalla holds a 1.0% NSR royalty on Aranzazu.

Endeavor

On March 9, 2026, Polymetals Resources Ltd. (“Polymetals“) Polymetals reported that mining of high-grade silver ore from the Upper North Lode at the Endeavor mine commenced in February, with stoping now underway and about 11,000 tonnes mined to date. Early production reconciliation from internal and third-party analysis indicates silver grades are materially higher than originally modelled, supported by confirmation of native silver in the ore. Polymetals also stated that, given the exceptional value of the Upper North Lode material, it plans to undertake a trial basis shipment of 30,000 tonnes of ore directly to a smelter to take advantage of highly attractive smelter terms and strong demand for silver. Direct shipment of ore has the potential to enhance realized metal value relative to concentrate production.

Metalla accrued 39 GEOs from Endeavor for the fourth quarter of 2025 and 272 GEOs for the 2025 fiscal year. Deliveries in the fourth quarter of 2025 were impacted by a fatal incident on site in October, which resulted in the temporary suspension of mining and surface operations.

Côté-Gosselin

On October 31, 2025, Metalla completed the acquisition of the remaining 0.15% interest in the Côté-Gosselin NSR royalty for total consideration of C$3.4 million in cash from an arm’s length seller. The acquisition increased Metalla’s total royalty percentage to 1.5%. This acquisition further consolidates Metalla’s exposure to one of Canada’s largest and lowest-cost emerging gold districts.

On February 17, 2026, IAMGOLD reported approximately 3,600 meters of drilling at the Gosselin deposit during the fourth quarter, for a total of 53,750 meters in 2025. The program was focused on converting a significant portion of Inferred Resources to the Indicated category. IAMGOLD announced that the results of the Gosselin exploration program will be included in an updated Mineral Reserve and Mineral Resource estimate in the second quarter of 2026, and will inform the planned updated technical report which will consider a larger scale gold mine with a conceptual mine plan targeting both the Côté and Gosselin zones over life of mine. The updated technical report is expected to be completed by the end of 2026. IAMGOLD also reported gold production at Côté gold mine in the fourth quarter of 125 koz (on a 100% basis), and expects production at Côté Gold in 2026 to be in the 390 – 440 koz (on a 100% basis). Continued ramp-up and planned expansion of the Côté operation are expected to support increasing gold production over time.

Future-Oriented Financial Information

This news release contains future-oriented financial information and financial outlook information (collectively, “FOFI“) about the Company’s revenues from royalties, streams, and other projects, which are subject to the same assumptions, risk factors, limitations and qualifications set forth in the paragraphs below. FOFI contained in this news release was made as of the date of this news release and was provided for the purpose of providing further information about Metalla’s anticipated future business operations. Metalla disclaims any intention or obligation to update or revise any FOFI contained in this press release, whether as a result of new information, future events or otherwise, unless required pursuant to applicable law. FOFI contained in this news release should not be used for purposes other than for which it is disclosed herein.

Technical and Third-Party Information

Metalla has limited, if any, information on or access to the properties on which Metalla(or any of its subsidiaries) holds a royalty, stream or other interest and has no input into exploration, development or mining plans, decisions or activities on any such properties. Metalla is dependent on (i) the operators of the mines or properties and their QPs to provide technical or other information to Metalla, or (ii) publicly available information to prepare disclosure pertaining to properties and operations on the mines or properties on which Metalla holds a royalty, stream or other interest, and generally has limited or no ability to independently verify such information. Although Metalla does not have any knowledge that such information may not be accurate, there can be no assurance that such third-party information is complete or accurate. Some information publicly reported by operators may relate to a larger property than the area covered by Metalla’s royalty, stream or other interests. Metalla’s royalty, stream or other interests can cover less than 100% and sometimes only a portion of the publicly reported mineral reserves, resources and production of a property.

Unless otherwise indicated, the technical and scientific disclosure contained or referenced in this press release, ‎including any ‎references to mineral resources or mineral reserves, was prepared in accordance with Canadian ‎NI 43-101‎, which differs significantly from the requirements of the SEC ‎applicable to U.S. domestic issuers. Accordingly, the scientific and technical ‎information contained or referenced in this press ‎release may not be comparable to similar information made ‎public by U.S. companies subject to the reporting and ‎disclosure requirements of the SEC.‎

“Inferred mineral resources” have a great amount of uncertainty as to their existence and great uncertainty as to ‎their ‎economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ‎ever be ‎upgraded to a higher category. Historical results or feasibility models presented herein are not guarantees ‎or expectations of ‎future performance.‎
